I guess maybe POSIX is wrong then :-) But as a random user I can type sync to the shell. > And report any errors to me, so if you're a database and I'm feeling > nasty I can maybe mess with you that way.

I think that's the real problem; if I open for write and fsync, then I should get status back that lets me know about my writes, regardless of who else asked for sync. Once that's fixed, then the 'others asking for sync' is much less of a big deal. I know, ENOPATCH.
